Use to slurp a CSV file into an Array of Arrays. Pass the path to the
file and any options CSV::new() understands. This method also
understands an additional :encoding parameter that you can use to
specify the Encoding of the data in the file
to be read. You must provide this unless your
data is in Encoding::default_external(). CSV will
use this to deterime how to parse the
data. You may provide a second Encoding to
have the data transcoded as it is read. For
example, encoding: "UTF-32BE:UTF-8" would read UTF-32BE data from the file but transcode it
to UTF-8 before CSV parses it.
